Digimat-FE generates realistic microstructures or reads microstructures from CT-scans to perform multiscale finite element analysis, providing an in-depth-view into composites.

Deep dive into the Digital Materials Laboratory: it’s all about multiscale analysis

Digimat-FE aims at advancing our understanding of the material behaviours to unlock the potential for innovation. From design to post-processing, the end-to-end solution streamlines every step to generate a detailed microstructure, perform accurate finite analysis (powered by Finite Element (FE) and Fast Fourier Transform (FFT) solvers) and gain in-depth insights into the microscopic mechanisms that affect the composite response. 

It allows you to create 2D and 3D models of a range of microstructures, from reinforced plastics and unidirectional composites to metals, ceramics and foams, that can be solved with a suite of different FEA interfaces and solver technologies for the most effective results. Key analysis tools include local field visualisation, probabilistic distributions and mean homogenised properties.

Value & Benefits: 

  • Optimise material properties to match specific industry requirements
  • Combine any types of resin and reinforcement to explore new composite formulations
  • Gain an in-depth view and understanding of the composites behaviours
  • Analyse effect of defects, damage, fibre/matrix debonding, etc.
  • Perform sensitivity analysis to better understand the material behaviour and optimize the microstructure.
